[RFC PATCH] arm64: Kconfig: enable ARCH_WANTS_THP_SWAP for all pagesizes

[Weilin Tong]

Currently, ARCH_WANTS_THP_SWAP was limited to 4K page size ARM64 kernels, but
large folios requiring swapping also exist in other page size configurations
(e.g. 64K). Without this config, large folios in these kernels cannot be swapped
out.

Here we enable ARCH_WANTS_THP_SWAP for all ARM64 page sizes.
